Over a year ago I raised the possibility of tracing every article back 
to the Main Page.  None in my random sample was more than five links 
away.  Thus if you trace Marie Antoinette and Michael Jordan back to the 
Main Page, the sum of their links will be a maximum distance. :-)
Maybe I'm misunderstanding you, but I don't think that last statement is correct. The number of links required to travel in one direction is not necessarily the same as the number required in the opposite direction. In this case, the paths from A to B and from A to C do not necessarily tell us anything about the path from B to C. Although if A is the Main Page, you can always cheat and use any of the navigation links that go there.
